摘要： A circuit for correcting a non-linear output of an electronic temperature sensor due to a non-linear drift over an operating range of temperature. The circuit includes a first circuit portion for adjusting a bias voltage of the sensor to a select initial voltage. The circuit also includes second circuit portion interfacing with the first circuit portion. The second circuit portion comprises at least one electronic element with a non-linear drift over the operating range of temperature, but in a direction opposite that of the drift of the temperature sensor. Thus, the drift of the electronic element alters the bias voltage over the operating range in a manner that compensates (at least partially) for the non-linear drift of the temperature sensor.

摘要： A linear temperature sensor that incorporates passive bipolar semiconductor devices and is capable of high accuracy over a very wide temperature range. The passive bipolar semiconductor device splits a voltage drop between the bipolar semiconductor and a resistor, such that the voltage drop varies approximately linearly in negative dependence on temperature. Optionally the linearity may be improved by providing sufficient current to produce a self-heating effect which compensates for non-linear deviations in performance at low temperatures.

摘要： A system for detecting a gap of unknown width, the system having an RF signal generator having an output interface that outputs an RF signal and that interfaces with an input portion of a test device that is electromagnetically connected with a first surface of a gap. The system also comprises an RF signal receiver having an input interface that receives an RF signal and that interfaces with an output portion of the test device that is electromagnetically connected with a second surface of a gap. The RF signal receiver generates an electrical output to an output interface when an RF signal is detected. A processor has an input interface that interfaces with the output interface of the RF signal receiver and the processor converts the electrical signal from the receiver into an indication to the user of the presence of a gap in the test device.
